%X Analyses on the absorption of aluminium by rice boiled in distilled water in a variety of containers, such as old and new aluminium pots, clay receptacles, stainless steel pots, and steel pots, were carried out. 10ˋg of rice was taken as a representative sample. Colorimetric analysis of classical methods was used to determine the concentration of aluminium. The control for aluminium was 350 ㊣ 130ˋ米g/g. The new aluminium pots had a concentration of 126 ㊣ 64ˋ米g/g, old aluminium pots had 314 ㊣ 128ˋ米g/g, new clay pots had 132 ㊣ 68ˋ米g/g, old clay pots had 195 ㊣ 137ˋ米g/g, new steel pots had 241.00 ㊣ 200ˋ米g/g, old steel utensils had 186.83 ㊣ 75.18ˋ米g/g, new stainless steel utensils had 294.83 ㊣ 163ˋ米g/g, and old stainless steel utensils had 289.00 ㊣ 75.155ˋ米g/g. Aluminium leaching was detected in all forms of new and old cooking utensils, and leaching was below and within the control concentration range. Old aluminium pots had the highest concentration of leaching while new steel pots had the least leaching of aluminium. However, the aluminium contamination of the foods tested was insufficient to constitute a hazard to health. 1. Introduction Aluminium is the third most abundant element in the earth＊s crust more than other elements [1每3]. From both health and medical points of view, oral ingestion of moderate doses of aluminum in healthy subjects has not been associated with any particular disease [4, 5]. With the possible exception of aluminum phosphate studies, aluminum appears to be associated with the brain lesion characteristics of Alzheimer＊s diseases, associated with aluminum in drinking water in several epidemiological studies [4每10]. The concentration of aluminium was confirmed in the brain tissue of a patient with Alzheimer＊s disease, Parkinson＊s disease, and encephalopathy [8每11]. An average of 30ˋmg of aluminium is consumed through water, food, and drugs daily [8, 11]. Before 1980, the daily intake of aluminium was reported to be 18每36ˋmg per day. According to recent data from the World Health Organization (WHO), the following was reported: a daily consumption of 9ˋmg of aluminium for teenage and adult females while for teenage and adult males a daily consumption of 12每14ˋmg of aluminium. In 1989, WHO reported that provisional tolerance weekly intake (PTWI) is 7ˋmg of aluminium per kilogram per body weight [9, 11每14]. Therefore, for a person with a weight of 60ˋkg, the acceptable dosage is not more than 60ˋmg/day. Some researchers reported the concern of the absorption of aluminium from cookwares, such as acidic food like tomatoes and basic foods
